Alternatively, in RPN mode, you can separate the operands with a space (#)
before pressing the operator key. Examples:
3.7#5.2 +
6.3#8.5 -
4.2#2.5 *
2.3#4.5 /
Using parentheses
Parentheses can be used to group operations, as well as to enclose arguments
of functions. The parentheses are available through the keystroke combination
„Ü. Parentheses are always entered in pairs. For example, to calculate
(5+3.2)/(7-2.2):
In ALG mode:
„Ü5+3.2™/„Ü7-2.2`
In RPN mode, you do not need the parenthesis, calculation is done directly on
the stack:
5`3.2+7`2.2-/
In RPN mode, typing the expression between quotes will allow you to enter the
expression like in algebraic mode:
³„Ü5+3.2™/
„Ü7-2.2`μ
For both, ALG and RPN modes, using the Equation Writer:
‚O5+3.2™/7-2.2
The expression can be evaluated within the Equation writer, by using:
————@EVAL@ or, ‚—@EVAL@
Absolute value function
The absolute value function, ABS, is available through the keystroke
combination: „Ê. When calculating in the stack in ALG mode, enter the
function before the argument, e.g., „Ê \2.32`
In RPN mode, enter the number first, then the function, e.g.,
2.32\„Ê
